The total number of all visitors landing at Goudier Island are recorded by UKAHT staff. The annual season total is provided.

Continuous measurements of meteorological parameters from the Frome Piddle; Pang Lambourn and Tern catchments, recorded between 2002 and 2006. Automatic weather stations were installed at 7 sites in these catchments to record hourly values of soil heat flux, relative humidity, atmospheric pressure, solar and net radiation (upward and downward short and long wave), rainfall, soil temperature at 10 and 30 cm, air temperature and wind direction and speed for differing periods at the varying sites. The instruments were installed as part of the NERC funded Lowland Catchment Research (LOCAR) Programme to provide comparable baseline metrological data across the LOCAR catchments.

This dataset includes manual measurements in centimetres from the surface of the soil of water table depth at the Climoor fieldsite in the Clocaenog Forest, north-east Wales. Water table depth was collected via water permeable tubes installed through the soil profile down to bedrock. Measurements were taken, usually every two weeks, using a tape measure and head torch to assist in seeing the water level in the tube. Data was collected by CEH staff and PhD students trained in the use of the methods. Climoor is a climate change manipulation experiment that utilises automated roof technology to produce drought and warming experimental treatments that reflect climate change predictions for the next 20-30 years. Data are available from May 2009 to March 2015. Full details about this dataset can be found at https://doi.org/10.5285/029c060d-a061-4e27-96ff-c0826351e7e3

This dataset contains measurements from smart sensors and cameras monitoring the movement of a single wooden dowel moving downstream in a flume. The following values in the x, y, and z directions are provided: velocity, linear acceleration, angular velocity, and filtered angular velocity. The quaternion components are also included. Four uniform flow conditions were tested, and the experiments were repeated about 50 times.

[This dataset is embargoed until October 1, 2026]. This dataset reports concentrations of six antibiotics—oxytetracycline, ciprofloxacin, enrofloxacin, sulfamethazine, ofloxacin, and norfloxacin—measured in surface water and wastewater from two catchments in India: Dera Bassi (Punjab) and Bhiwadi (Rajasthan). Samples were collected at four time points between May 2022 and June 2023 from the River Ghaggar and wastewater effluent sites.

This dataset contains a timeseries of pressure (dbar), sea pressure (dbar), and depth (m), within the inner regions of four UK estuaries: Conwy, Dyfi, Milford Haven and Kent. Data was collected between 2020 and 2023. The temporal resolution is either 1s or 10 s. Specific information on the data locations, deployment methods, units and reference levels, data structure, and quality control can be found in the accompanying supporting documentation (read_me.docx).

This dataset includes litterfall data from the experimental plots at the Climoor field site in the Clocaenog forest, NE Wales. Litterfall (natural senesced plant material) was collected in litterfall traps (12 x 7.5cm pots standing slightly proud of the soil/litter surface, emptied monthly). Litterfall was calculated by drying the contents of the traps and weighing the samples; values were calculated for each quadrat (total weight (g) only) and for each plot (total weight (g) and weight per metre squared (g/m2)). Data spans the periods Oct 1999 to Jan 2004 and July 2008 to June 2011. Data was collected by CEH staff and PhD students trained in the use of the methods. Climoor is a climate change manipulation experiment that utilises automated roof technology to produce drought and warming experimental treatments that reflect climate change predictions for the next 20-30 years.

Erosion risk mapping showing soil erosion potential (tonnes/yr) using the Soil Water Assessment Tool (SWAT) for the Yorkshire River Derwent, UK. The modelled data includes 29 years of weather data (1990-2019). Outputs were validated using SUFI2. This dataset builds on previous modelling using SCIMAP.

Datasets consists of the results of Computational Fluid Dynamics (CFD) flow simulations for a section of the South Saskatchewan River, Canada. The aim of these CFD simulations was to investigate the effect of dunes on the depth-averaged and near-bed flow fields. Modelling was carried out using the open source CFD package OpenFOAM to solve the three-dimensional Navier-Stokes equations. The dataset consists of two files, one with simulation results for a river bed characterised by alluvial bedforms (dunes) and one for a smooth river bed without dunes. This work was part of NERC project NE/L00738X/1. Digital Surface Models (DSMs) were constructed using imagery obtained on four occasions (13th May 2015; 2nd Sept 2016; 8th June 2017; and 12th June 2017). Full details about this dataset can be found at https://doi.org/10.5285/7db04405-2f5e-4543-aa94-948ddbcd588a

Data comprise earthworm survival and weight change data after 28 days exposure to nanomaterials and reproduction data after 56 days exposure. Concentrations of zinc and silver in extracted soil pore water and ultra-filtered pore waters are reported as well as pH and dissolved organic carbon data. The body concentration of zinc, silver and titanium in three earthworms from each replicate after 28 days exposure are included. Data were generated from a laboratory exposure experiment of earthworms (Eisenia fetida) to soil amended with sewage sludge. The sewage sludges were from a wastewater treatment plant (WWTP) treated with nanomaterials (ENMs) or metal/ionic salts. Sewage sludges were generated with either no metal added to the WWTP influent (control), ionic ZnO, AgNO3 and bulk (micron sized) TiO2 added (ionic metal-treated) or ZnO, Ag and TiO2 ENMs added (ENM-treated). A sandy-loam soil was amended with the treated sewage sludge and aged in outdoor lysimeters for six months. Earthworms were exposed to the aged mixtures and a dilution of the mixtures (using control soil-sludge mix).
